This article is for Gantt Charts Data Center.
Problem
I installed the Gantt Charts app but it doesn’t appear in the list of apps in Jira.
Solution
Gantt Charts is an extension of our main app Structure - Gantt charts is the built-in functionality inside structures. Gantt Charts cannot work without Structure, so you need to install Structure on your domain as well.
Structure can be found on Atlassian Marketplace; its vendor is Tempo Software: https://marketplace.atlassian.com/apps/34717/structure-by-tempo-jira-portfolio-management-ppm?hosting=datacenter&tab=overview
